目的了解厦门市居民膳食中铅、镉、汞摄入量,评估厦门市居民膳食铅、镉、汞的安全性。方法对厦门市市售食品中铅、镉、总汞含量进行监测,结合居民膳食摄入量调查结果,对居民膳食中铅、镉、汞暴露水平进行评估。结果厦门市居民平均膳食中铅(每周)、镉(每月)和总汞(每周)暴露量分别为10.0、27.6和0.9μg/(kg·bw),占(原)PTWI/PTMI的40.0%、110.6%和22.5%;平均膳食铅暴露的暴露边界比(MOE)为0.86。结论目前厦门市居民膳食中铅和汞的摄入量是安全的,但镉的膳食暴露量问题较严重,应该加强相关产品中镉的监测及膳食指导工作。
Objective To understand the dietary intake of lead, cadmium and mercury in Xiamen residents and evaluate the safety of dietary lead, cadmium and mercury in Xiamen residents. Methods The contents of lead, cadmium and total mercury in the foodstuffs in Xiamen were monitored. The dietary intakes of lead, cadmium and mercury were evaluated according to the dietary intake of residents. Results The average dietary exposures of lead (weekly), cadmium (monthly) and total mercury (weekly) in Xiamen residents were 10.0, 27.6 and 0.9 μg / (kg · bw) respectively, accounting for 40.0%, 110.6% and 22.5%, respectively. The average MOE of dietary lead exposure was 0.86. Conclusion At present, the intake of lead and mercury in Xiamen residents is safe, but the problem of dietary exposure to cadmium is more serious. Cadmium monitoring and dietary guidance should be strengthened in related products.
